Please note that I may take a long time to get back to you: occasionally it will be months; my personal life dictates how much time I can spend on this project, and while it's easy to keep the list maintained it's a lot more time-consuming to look into and respond appropriately to all the emails I get regarding the list. However, I will respond eventually (unless I'm fatally involved in a low flying helicopter accident, or something! (Or perhaps my mail gets deleted, or it gets filtered into my junk mail folder, or... well, there's a lot of reasons why I might not get back to you, now I come to think about it. But, the point is, since at least 2001 I don't think I've ever not replied to a mail about the list)).
